A lane marker recognition method comprises the steps of inputting an image
including a lane marker, extracting luminance change points in the image,
and estimating the position of the lane marker using the extracted edge
points. The edge extracting step includes calculating an angle of
orientation of each of the edges and the lane marker position estimating
step includes extracting edge points that are oriented toward a vanishing
point of a road, from among the edge points extracted in the edge
extracting step.
